On the standpoint of chronobiology, the effect of 50 Hz magnetic field of (1.04 ±0.17) mT on the circumnutation of the stem of Arabidopsis thaliana has been examined experimentally. When the stem was not exposed by the magnetic field, there existed the main frequency of 9.2×10^<-5> Hz having the largest power and frequencies from 1.3×10^<-5> Hz to 1.97×10^<-4> Hz of low powers in the oscillation spectrums of the circumnutation. In the oscillation of the stem exposed by the field, the frequency of the largest power was 1.3×10^<-5> Hz and those from 2.60×10^<-5> Hz to 1.92×10^<-4> Hz of relatively large powers were found. As a result of the examination with frequency modulation model proposed in this research, it was presumed that 50 Hz magnetic field might enhance the circadian rhythm of the circumnutation or induce an oscillation like diurnal change, and that one or both of them might consequently modulate the main frequency in the absence of the field. This implies that Arabidopsis thaliana may have a sensibility like the diurnal change which responds to 50 Hz magnetic field.
